IMPROVEMENT IN PUMPS FOR DRIVEN WELLS.

Specification forming part of Letters Patent No. 143,345, datedSeptember 30, 1873 application filed July 23, 1873.

To all whom it may concern: A

' Be it known that we, J oHN W. HARRING- TON, of Cincinnati, Hamiltoncounty, State of Ohio, and JOSEPH A. YINGLING, of Hamilton, Butlercounty, State of Ohio, have invented a certain new and usefulImprovement in Pumps for Bored, Drilled, Driven, and other Wells, ofwhich the following is a specification:

Our invention consists, in connection with the sectional pipes of adrive-well or other pimip, of a conically-formed coupling or sleevejoining two sections together and fitted with a check-valve, which canbe lowered into its place and tightly secured after the well is driven,and which can be removed conveniently and at any time from the wells forrepairs, the valve-seat being fitted exteriorly with a packing-ring tomake a tight joint by crowding down into the conical bore of the sleeve,and constructed with a bailover the valve for the attachment of a hookedrod to withdraw it from the sleeve. The object of this coupling andvalve is, by the cylinder and working parts of the pump, to be driven inand located at any required depth in the pipe, and thereby obviate thenecessity of digging down any part of the distance to place the cylinderwhere atmospheric pressure will suffice to supply the pump with water,for without this device and by the ordinary method of making wells fordriving pumps, where the water is low in the ground, it is necessary todig a well or pit down within, say, twenty to thirty feet of where thewater is expected to be found, and when the pipes are drivenin thebottom of this pit until water is reached, then the cylinder or workingparts of the pump are attached to the pipe at the bottom of this pit.

The accompanying drawing is a section of the part of a drive-well pumpembodying our invention.

As is customary with drive-well pumps the pipes are driven into theground after preparatory boring, drilling, or otherwise, the lowerriorly for the occupation of and proper connec-' tion with a check-valveandseat, D D. Over the seat a bail, D, is formed, which can be suspendedupon a hooked rod, by which the valve-seat may be lowered into place inthe well after the driving or other adjustment of A the pinup-pipes, andby which the hooked rod may draw out the valve-seat for rep airs. Uponthe exterior of the seat an annular ring of elastic substance is fittedand provided to form a packing, E, to make a tight joint between thevalve-seat and the conical coupling, the seat in 7 use being forced downso that the packing-ring is so tightly bound between the surface of theseat and coupling as to prevent the passage of air or water at thisjoint.

An obvious modification of this device, which is simply a reversion ofparts, is one in which the packing-ring is secured in the coupling, andthe smooth conical surface of the seat forced down into it to make thejoint.

We claim The internally-tapered coupling 0, which rigidly connects thesuction-pipe A and barrel B of the pump, in combination with thecheckvalve and seat D D D and the protruding packing-ring E, which ispermanently secured in an annular recess of either the valve-seat or thecoupling 0, substantially as and for the purpose specified.

In testimony of which invention we hereimto set our hands.
